Re: [MirageOS-devel] Fwd: [Xen-devel] RFC: Cleaning up the Mini-OS namespace

The library work is waiting for the ARM patches to be accepted first.
The latest version is on my "devel" branch (which is regularly rebased
against Xen master):


In terms of upstreaming, the most obvious thing that needs doing is
modifying Xen's stubdoms to use the library. Currently, they do some
horrible make stuff to reach over and grab what they need from the
extras/mini-os directory...

Ian Jackson (I think) mentioned splitting Mini-OS into a separate
repository, which would help a lot too.
